XaoS is a fast, portable, real-time, and interactive fractal zoomer. It displays the Mandelbrot set (among other escape time fractals) and allows you zoom smoothly into the fractal. Various coloring modes are provided for both the points inside and outside the selected set. In addition, switching between Julia and Mandelbrot fractal types and on-the-fly plane switching is provided.

xgrk provides the possibility to change keyboard mapping with alt-shift or meta-shift combinations or by clicking on the flag image. You will be able to write greek in X programs like netscape or xedit. Keycodes are auto-loaded on startup so it should work with all unices and keyboard layouts. Fonts are not included.

Xnee can record, distribute, and replay X (X11) protocol data. This
is useful for automated tests of applications or benchmarking of
applications. Think of it as a robot. A GUI, a Gnome Panel Applet, and a
CLI are available, as well as bash functions.

The GUIShell project is a collection of utilities facilitating the use of the GTK+ toolkit in shell scripts through the gtkshell utility. The ACE configuration environment provides sample scripts utilizing gtkshell for desktop utilities. rootcat provides the ability to display messages to the root window using Xft, allowing one to write status display scripts.

The aim of LucED is to be a fast and responsive X11 text editor with a simple but powerful user interface similar to NEdit. It uses Lua as an embedded scripting language, and features syntax highlighting that is configurable via PCRE regular expressions with arbitrarily nested patterns.

subtle is a grid-based manual tiling window manager with a strong focus on easy but customizable look and feel. In comparison to other tiling window managers, subtle has no automatic tiling of the screen size in any way. Instead, windows are arranged according to positions inside of a grid. These positions are called gravities.

Scheture is a hierarchical schematic capture
system with built-in netlisters for Spice and
Verilog. It has built-in plotting for Postscript, HP PCL and
HP GL/2 printers and plotters. It includes a set
of symbol primitives, and allows user-defined
symbol primitives to allow for extensive
customization of primitive properties. The system
supports wire buses and iterated instances. The
system also supports global pins and implicitly
connected pins on a specific sheet. Supported
platforms include Solaris and Linux (32- and 64-bit).
